Fitting the Marauder bumber should work, that will certainly save you cutting holes in the bumper to get the lights to fit right. Just make sure you are fitting the Maurader fog light on thee aswell. Then it'll simply be a matter of wiring it all up correctly.
As for the tailights, i don't know if the Maurader ones will fit... you'd have to check with the dealership's parts department to see if parts are the same is my thought on that one.
Hope that helps!
